i just checked the zoom flow using debug. The zoom action goes through the ViewOptions class http://opengrok.libreoffice.org/xref/core/sw/inc/viewopt.hxx#163 it appears zoom is stored in nZoom, which is a sal_uInt16<http://opengrok.libreoffice.org/s?defs=sal_uInt16&project=core> representing percentage.
So according to what you say, threre should be a different accessible object or struct that holds the zoom with finer precision. If so, then what object or class holds "the absolute source of truth" for data regarding VCL elements?
